WALL EXERCISING APPARATUS.

Specification of Letters Patent.

Patented Feb. 11, 1913.

Original application filed December 8, 1910, Serial No. 596,308. Dividedand this application filed February 8, 1912, Serial No. 676,248. RenewedJanuary 6, 1913. Serial No. 740,544.

To all whom it may concern:

Be it known that I, ROBERT REACH, citizen of the United States, residingat Springfield, Massachusetts, have invented certain new and usefulImprovements in WVall Exercising Apparatus, of which the following is aspecification, which is a division of application Serial No. 596,308,filed December S, 1910, exercising apparatus.

My invention relates to weight carriages.

for wall exercising machines.

In weight carriages of the under-lift type an objection has beenexperienced in that the weight sect-ions are liable to drop from thecarriage or from the section next above, this being due to the releaseof the locking device between the sections because of the vibration ofthe weight carriage, and I have sought to remedy and eliminate thisvibration by my improved construction and also to simplify theconstruction of the weight sections and the locking means between them.

The invention consists in the features and combination and arrangementof parts hereinafter described and particularly pointed out in theclaims.

In the accompanying drawing, Figure 1 is a front view of the lowerportion of an exercising machine embodying my invention, and Fig. 2 is aside view of the part shown in Fig. 1; Fig. 3 is a sectional viewthrough the weight sections, the carriage being shown in frontelevation; Fig. 4 is a plan view of one of the weight sections.

IVhile I have illustrated my invention in connection with a wallapparatus having a pair of weight carriages one behind the other, itwill be understood that I do not limit myself in this respect.

In the drawings, 3 represents the guide rods of the wall apparatus, and13 the weight carriage consisting of a plate having lugs or bosses 15,through which the guide rods pass to guide the carriage in its verticalmovement.

11 indicates the weight carriage pulley mounted on the weight carriageand this pulley instead of being arranged with its axis in the sameplane with the plane passing through from side to side, and in which theguide rods lie, is arranged with its axis extending from front to rear,or at right angles to the plane of the guide rods. The

advantage secured by this over the arrangement of the weight pulley, asheretofore used, is that the points of suspension on the operating ropeare brought close to the guide rods instead of at a point centrallybetween them, and this has the effect of eliminating vibration.

In the old form in which the pulley lies with its axis in the planepassing through the side guide rods the weight carriage as it moves-upand down along the guide rods is liable to vibrate or tip because thepoint of support or contact of the weight pulley with the loop of therope being in effect a pivot point, and being centrally located betweenthe guide rods, will allow lateral oscillation of the weight carriage,and cause it to bind first at one side and then at the other upon theguide rods, thus causing more or less vibration. The disadvantage ofthis vibration is that aside from irregularity in the movement of theweight carriage, the weight sections are liable to be dropped for thereason that the vibration will cause the lock or fastening devicebetween one weight section and the next above or between one weightsection and the carriage plate to be loosened, allowing the weightsections to fall. I have also improved the construction and arrangementof the weight sections and their locking devices, as will now bedescribed. The weight carriage 13 is provided with a lug having a head30, adapted to pass down into a recess in the upper weight section 31,wherein the said lug is locked by a slide 32, carried by the weightsection and having its ends projecting at 33 and provided withenlargements so that by striking these enlargements with the. foot theslide may be shifted in one direction or the other so as to lock theweight section to the carrier or to unlock the same.

The slide is shown in plan view in Fig. 4 and it is slottedlongitudinally to receive the guide bars 3 and allow movement thereon.The slide is held to the weight section by a cover plate 34 secured byscrews 35. Each section, except the lowermost, is provided with a lug 30similar in all respects to the lug of the weight carriage and adapted topick up or release the weight section next below it. It will be observedthat the weight sections are of elongated form and where two Weightcarriages are employed as shown, the Weights of one carriage lie par- ,vallel to those of the other and occupy comparatively little of the roomfrom front to rear. An additional advantage of my arrangements of thepulleys is that the weight carriage may be located close to the walltogether with the guide rods and brackets.

hat I claim is 1- 1. In combination in an exercising machine, a Weightcarriage and a weight section attached thereto removably, said weightcarriage having a projecting lug to enter the weight and a slide movablelongitudinally on the Weight section for engaging the said lug to securethe weight section to the weight carriage, substantially as described.

2. In combination in an exercising machine, a weight, a carrier thereforand means for attaching the weight removably to the carrier comprising aslide or plate on the weight having its ends projecting to be pressedupon and slide longitudinally, substantially as described.

3. In combination in an exercising machine, a weight carriage, arecessed weight to receive a lug from the carriage or weight above, aslide or plate to engage said lug, and means to hold the slide in place,substantially as described.

In testimony whereof, I affix my signature in presence of two witnesses.
